Cho Aniki coming to download services here (the PSP game, Cho Aniki Zero, also came out here, and it's PSN-exclusive) is far less surprising, because retailers aren't dedicating any amount of shelf space to those; I'm surprised more "anime" games don't come out in the US as download-only titles considering what happened with Atelier Rorona. But Otomedius X is going to be a retail release just like DeathSmiles (another shmup involving girls, though those ones wear a lot more clothes) was.
